A new liftgate ajar switch is needed and the harness connector should be repaired.
Chafed wires in the neutral position switch harness can cause an inoperative or intermittent operation of the speed (cruise) control. The harness wires need to be repaired and routed away from the throttle cable bracket on the transmission.

Jeep issued a recall on some ABS equipped vehicles because seals inside the master cylinder fail. When the seals fail, a loss of pressure is detected causing the ABS hydraulic pump to cycle on more frequently or run continuously. This will lead to premature failure in the hydraulic pump. There is a lifetime warranty on the seals and the hydraulic pump motor. Normal braking will still work but brake pedal effort may increase.
